Hi,
Thanks for posting your question on Microsoft Q&A forum!
Based on your description, it sounds like there might be an issue with the configuration of Rights Management Services (RMS) in relation to Outlook Web App (OWA). You can do the following to troubleshoot:
- run the following command to check the RMS configuration:
Get-IRMConfiguration
- Make sure that OWA IRM (Information Rights Management) is enabled.
Set-OWAMailboxPolicy -Identity "OWA Mailbox Policy Name" -IRMEnabled $true
- Verify that your OWA virtual directory is configured correctly. You can do this by running:
Get-OWAVirtualDirectory | FL
